Abstract
A cross-linked polyolefin resin foam of the present invention has a total light transmittance and a thickness that satisfy a predetermined condition, and has a reflection color difference Δ* of −10 to 16, a reflection color difference Δa* of −3 to 3, and a reflection color difference ΔL* of 50 or more. According to the present invention, there can be provided a cross-linked polyolefin resin foam that can suppress a change in color tone of transmitted light while ensuring transparency, and a pressure-sensitive adhesive tape, layered product, formed product, and display member that include such a cross-linked polyolefin resin foam.
Claims14
A cross-linked polyolefin resin foam, satisfying the following equation (1), when a total light transmittance measured with a haze meter in accordance with ASTM D1003 is taken to be y % and a thickness is taken to be x mm:
- y≥29.631×x−0.352 (1)
- and having a reflection color difference Δb″ of −10 to 16, a reflection color difference Δa″ of −3 to 3, and a reflection color difference ΔL″ of 50 or more, wherein the reflection color differences Δb*, Δa*, and ΔL* are measured in accordance with JIS Z8722.
